[boost] Singleton/Multiton

Currently, my dependency lifetimes, when set to use lazy creation, only 
create the object when the first pointer is created, instead of creating 
whenever the first dependency is created.  I was thinking that it might 
make sense to extend this even further and have it only created the 
first time a member is accessed through the singleton.  This would 
simply require one more intermediate pointer type.  In addition, this 
intermediate pointer could function to lock the operations performed on 
the singleton/multiton.  Are there any drawbacks to this plan, or should 
I implement it?
